No Lock-Up condition
Falling out of lockup when hot
Fluid blown out fill tube
Lockup immediately after 2nd gear
Excessive pump bore-to-valve clearance allows TCC signal oil to leak past the spool, preventing lockup or causing lockup to disengage when hot.
Additionally, converter feed can leak past the excessive clearance, combine with signal oil and cause premature lockup.
These improved TCC apply valves with Teflon® seals will eliminate bore cross leakage.
SONNAX PRODUCT SUMMARY;
Features & Benefits
TCC apply valve for 4L60 & E non-PWM units is made from hardened steel to match the OEM material.
• Precision valves have a Teflon® seal to eliminate cross leaking of converter signal oil and converter feed oil.
Vehicles with GM 200-4R, 4L60 and 4L60-E transmissions have numerous converter overheat lockup complaints. These include no lockup or lockup immediately after 2nd Gear when fluid warms up, caused by valve bore wear. Frequently, the solenoid will have no control over the valve's position. Often converter feed oil will leak past the OE spool, which, added together with orificed signal oil will be more than the solenoid can exhaust. This may completely stroke the valve into the lockup position and create a "no power" or "no brake cancel" condition. Oil cross-leaks may float the valve into a mid-way position and restrict cooler flow, which burns up the converter. Sonnax TCC apply valve kit 77805-K will eliminate the bore cross-leakage. This precision valve has a PTFE seal to prevent the cross-leaking of converter signal and converter feed oil.
Hardened steel valve matches OE material
PTFE seal eliminates cross leaking of converter signal oil and converter feed oil
